Hole Locations and a Filling Method for Coprime Planar Arrays for DOA Estimation [PDF]
IEEE Communications Letters, 2021 Coprime linear arrays (CLAs) have drawn lots ofattention. Efforts have been made to reveal the hole locations inthe difference coarrays of CLAs, based on which many methodshave been proposed to fill the holes, lengthening the consecutivedifference coarray part and increasing the effective degreesof freedom (DOFs). Compared with CLAs, two dimensional(2D)

A High Resolution Optimum 2D Coprime Planar Array
2022 IEEE 19th India Council International Conference (INDICON), 2022 Designing a new class of rectangular two-dimensional sparse array to enhance the signal resolving capabilities with a limited number of sensors has always been a challenge. We explore the non-uniformity of the sparse arrays to enhance the Degrees of Freedom (DOF) by considering the under-determined cases using the concept of the virtual array.

Two-Dimensional DOA Estimation for Coprime Planar Arrays Based on Self-Correlation Tensor
Mathematical Problems in Engineering, 2022 In the coprime planar array (CPA), the existing tensor DOA estimation has the problem that the statistics are not fully utilized. We propose a two-dimensional DOA estimation method based on tensor self-correlation, which realizes the high-resolution and high-precision joint estimation of elevation angle and azimuth angle.
